Overview

Overview

Metabolic acidosis is a state in which the blood pH is low (less than 7.35) due to an increased blood concentration of H+.

Life Threatening Causes

Common Causes

Normal Anion Gap (Hyperchloremic Acidosis)

The mnemonic for the most common causes of a normal-anion gap metabolic acidosis is “DURHAM.”

High Anion Gap

The mnemonic “MUDPILES” is used to remember the causes of a high anion gap.
